  • Medium bowl
  • Measuring cup
  • Mold (plastic Easter eggs, muffin tin, plastic craft balls, etc)



  • Combine all dry ingredients in a medium-sized mixing bowl. Whisk well, removing any clumps.
  • In a separate bowl or measuring cup (preferably one with a spout), combine the wet ingredients and add food coloring if you desire.
  • Add in the liquids slowly. (I didn’t use a measuring glass with a spout, but you should! It will be much easier to control the amount of liquid as it goes in.) Stir the liquid into the dry mix as you go, and try to keep the fizzing and bubbling to a minimum.
  • Once you’ve added all of the liquid into the dry mixture, you’re ready to fill your molds. If you find the two sides of your bomb aren’t sticking together, or they are falling apart when you remove them from the mold, you might need to add a tiny bit more water to your mixture and start the molding process over again.
  • Remove the bath bombs from the mold, place them on parchment paper, and allow them to dry overnight. Once dry, wrap the bombs individually in plastic, or store in a container until you’re ready to use them.


You'll want to remove the bath bombs from the mold as soon as you press the sides together. If left to harden in the mold overnight, you might have trouble getting the mold off altogether, thanks to the coconut oil. 
If that happens, use a warm hairdryer to soften the oil slightly and allow your bath bombs to pop out of the mold.
